Suggest to your nice friendly Qt developpers that they do as the xforms
frontend does in this regard. If they want to be clever, they could create
a CheckedWidget class that interogates the contents and automatically
displays them as red if they are invalid. Certainly, it shouldn't prohibit
you from inputting them ;-)
